Abstract

A graft fixation device combination. The device is useful for affixing a tissue graft to a bone or other body surface. The fixation device has two implantation members connected by a graft retention member. The retention member optionally has at least one lateral wing member extending therefrom. The implantation members have longitudinal passageways therethrough. The graft fixation device also has an insertion member extending from the distal end of each implantation member, the insertion member having a longitudinal passage having a distal blind wall. The passages of the implantation members and the insertion members are in communication with each other, and may be mounted onto insertion members.

Claims

1. A method of mounting a matrix to a bone, the method comprising:

providing a graft fixation device comprising;

a first implantation member, said implantation member having a longitudinal axis, a proximal end, a distal end, an outer surface, a longitudinal passage therethrough, a proximal opening and a distal opening, wherein both openings are in communication with the passage;

a second implantation member, said implantation member having a longitudinal axis, a proximal end, a distal end, an outer surface, a longitudinal passage therethrough, a proximal opening and a distal opening, wherein both openings are in communication with the passage;

a retention member connecting the first and second implantation members, the retention member having a central section, a first end section extending from the first implantation member and a second end section extending from the second implantation member; and

,

an insertion member extending from the distal end of each implantation member, wherein the insertion member has a proximal end, a distal end, an outer surface, a proximal opening and a longitudinal passage in communication with the proximal opening, wherein said longitudinal passage has a distal blind end, and wherein the longitudinal passage of each insertion member is in communication with the longitudinal passage of the respective implantation members; and

,

at least one wing member extending from the retention member;

accessing a bone;

positioning a matrix member to the surface of the bone, said matrix member having a top surface and a bottom surface;

mounting the graft fixation device to an instrument having a shaft having a distal end, a proximal end, and distal mounting pins extending from the distal end of the shaft, wherein the pins are engaged in the longitudinal passages of the implantation members and insertion members; and

,

manipulating the shaft such that the insertion members are caused to penetrate the matrix and the bone, thereby causing the implantation members to engage the bone, and the retention member to engage the matrix such that at least a section of matrix is maintained substantially in contact with the bone.

2. The method of claim 1 wherein the implantation members have a series of ridges extending from the outer surfaces thereof.

3. The method of claim 1, wherein the retention member comprises a semicircular configuration.

4. The method of claim 1, wherein the implantation members comprise a substantially cylindrical configuration.

5. The method of claim 1 wherein the insertion member comprises a bioabsorbable material selected from the group consisting of polylactic acid, polyglycolic acid, tricalcium phosphate, calcium phosphate, tetracalcium phosphate and hydroxyapatite, and copolymers, mixtures and blends thereof.

6. The method of claim 1 wherein the insertion member comprises a biocompatible material selected from the group consisting of titanium, stainless steel, ceramic, and Nitinol.

7. The method of claim 1 wherein the fixation device comprises a bioabsorbable polymer.

8. The method of claim 1 wherein the fixation device comprises two opposed wing members extending from the retention member.

9. The method of claim 1, wherein the implantation members comprise a cylindrical shape having a distally extending frustoconical end.

10. The method of claim 1, wherein the insertion members have a conical configuration with a distally extending tip portion.

11. The method of claim 1, wherein the retention member comprises an elliptical configuration.

13. The method of claim 1 wherein the implantation member comprises a bioabsorbable polymer selected from the group consisting of polylactic acid, polydioxanone, polycaprolactone, polygalactic acid, polyglycolic acid, and combinations thereof.

12. The method of claim 12, wherein the retention member comprises an elliptical configuration.
